# Best Practice is to use a remote state file on S3 plus a dynamodb concurrency lock
# https://www.terraform.io/docs/language/state/remote.html
# https://www.terraform.io/docs/language/state/locking.html

# Create a dynamodb table for locking the state file during terraform apply.
# This can be reused by multiple terraform projects just by referencing the resource.
